Hi,This is a button shield I am creating for use with a Digispark.As I have never designed a PCB, I just want to make sure that this looks like it should function properly. Other than having GND conne...
Using 74HC4051, the eight inputs are connected together to a sine signal (only for testing so the inputs are connected together), and the sine signal measured at the output is as shown in the figure, ...
I have a very small and thin PCB I am trying to design to work in a very small space. Essential trying to only solder a SOT-23 to another SMD chip, hoping to mount them on either side of a double laye...
Hi, I'm an electrical engineer major college student and I want to go into PCB design. I don't know much literally just started searching up things and I'm not even familiar with term...
Why is there a resistor and capacitor connected in parallel at both ends of the microphone (the part circled in red)? What is the role of these two components here? Can they be removed?
The circuit board I made is powered by the USB port of the computer. I feel that the voltage should be relatively stable. Is it necessary to add a voltage regulator circuit? I wanted to add a 7805 thr...
